-美国人在读这两个音的时候，常常会在末尾加上一个 `ʳ`，但，也不是每一次都会加上 `ʳ`。初学者容易矫枉过正，遇到这两个音就加上 `ʳ`，比如，可能会把 *focus*<span class="speak-word-inline" data-audio-us="/audios/focus-us.mp3"></span>读成 `fəʊkəʳs`。
+美国人在读这两个音的时候，常常会在末尾加上一个 `ʳ`，但，也不是每一次都会加上 `ʳ`。初学者容易矫枉过正，遇到这两个音就加上 `ʳ`，比如，可能会把 *focus*<span class="speak-word-inline" data-audio-us="/audios/focus-us.mp3"></span>错读成 `fəʊkəʳs`<span class="speak-word-inline" data-audio-us="/audios/focurs-us.mp3"></span>。
 
 有些词典，常常会用 `ɜ` 标注 `ə` 这个音。另外，针对美式发音，`əʳ` 会被写成 `ɚ`，`əːʳ` 会被写成 `ɜː` 或者 `ɝ`。
